ª
If you did the test correctly and got an OK message on all three tests, the
laser unit has been successfully calibrated.
8.1.2 Calibration-Check with use of an external power
meter
Equipment Needed: Certified traceable power meter that can measure a min-
imum of 10 Watt.
WARNING
You must wear the laser protective goggles supplied with the laser unit during
the entire calibration procedure!
¾
Connect an optical fiber to the SIROLaser.
¾
Make the optical fiber point to the measuring head of the power meter.
Keep a minimum distance of 20 mm between the optical fiber and the
surface of the measuring head. This will prevent damage to the
measuring instrument due to the high energy density resulting from the
small fiber diameter.
¾
Wear the laser protective goggles and verify that the entrance to the room
where the calibration is being performed is controlled by an interlock
device or is locked.
¾
Switch on the SIROLaser and go to the “SETUP AREA”.
¾
Select “SERVICE”.
¾
Check to see that the fiber is neatly cut, and that the laser beam projects
a red circle. The circle must be as well defined as possible.
The first test (1 W) is highlighted.
¾
Use the “RIGHT ARROW” key to select the test you want to perform
(1 W, 3 W, 5 W). To quit the test area, press the “LEFT ARROW” key.
Test for 1 W
¾
Release radiation with the foot switch or finger switch until the message
OK appears. Check whether the power meter reading is within the
permissible range of 1 W +/- 20 %.
Test for 3 W
¾
Release radiation again until the message OK appears. Check whether
the power meter reading is within the permissible range of 3 W +/- 20 %.
Test for 5 W
¾
Release radiation again until the message OK appears. Check whether
the power meter reading is within the permissible range of 5 W +/- 20 %.
¾
Quit the calibration menu by pressing the “LEFT ARROW” key.
If the test procedure runs without errors, the message OK will appear for each
test, and the values measured on the power meter will be within the permis-
sible range. In this case, the unit has been successfully calibrated.
